使用GitLab CI和Python' onbuild'图片,requirements.txt中的包似乎没有安装

我试图通过测试项目Gitlab CI熟悉https://gitlab.com/khpeek/CI-test环境。该项目具有以下.gitlab-ci.yml

image: python:2.7-onbuild
services:
  - rethinkdb:latest
test_job:
  script:
    - pytest

问题是CI管道中的test_job作业失败,并显示以下错误消息:

但是,存储库中有一个requirements.txt,其中包含单行pytest==3.0.7。但是,在python:2.7-onbuild图像的Dockerfile中,我认为pip install -r requirements.txt应该在构建时运行。那么为什么找不到pytest

2 个答案:

答案 0 :(得分:1)

如果查看与之关联的Dockerfile,您会看到[aria-label="Story"] { background-color: rgb(0, 0, 255); } [aria-label="Story"] ^ [aria-label="Story"] { background-color: rgb(255, 0, 0); } onbuild命令的一部分。如果要从第一个容器创建新容器并安装一堆需求,这将非常有用。因此,pip install -r requirements.txt命令不会在CI管道的容器中执行,如果是,它将在最开始执行,甚至在克隆gitlab存储库之前。

我建议您以这种方式修改pip install -r requirements.txt文件

.gitlab-ci.yml

问题似乎是间歇性的:尽管第一次运行测试需要61分钟(最初失败),现在大约需要一分钟(见下面的屏幕抓取)。

作为参考,测试存储库位于https://gitlab.com/khpeek/CI-test。 (我必须添加before_script一些pip install来使作业成功。)
